Abstract
The utility model discloses a pressure-reduction and noise-reduction V-shaped regulating ball valve, which comprises a valve body (6), a valve seat (2), a pressure-reduction and noise-reduction V-shaped regulating ball (4), a valve rod (5) and a valve cover (1), wherein the valve cover (1) is arranged on the valve body (6) through a sealing ring (3); the pressure-reduction and noise-reduction V-shaped regulating ball (4) and the valve seat (2) are arranged in a valve cavity of the valve body (6); the valve rod (5) is connected with the pressure-reduction and noise-reduction V-shaped regulating ball (4); and enough V-shaped holes (8) and a plurality of zigzag small holes (7) are formed on one side of the pressure-reduction and noise-reduction V-shaped regulating ball (4) and communicated with each other. Flow regulation and pressure gradual reduction are realized at low flow speed by design of enough V-shaped holes and zigzag small holes, the phenomenon of non-regulation when a medium flows at high speed and the opening degree is 30 percent is avoided, pressure on a downstream valve seat is reduced, noise is reduced, the valve is convenient to disassemble or maintain, regulation performance is improved, and service life is prolonged.
Description
Technical field
The utility model belongs to universal machine valve manufacturing technology, is specifically related to a kind of step-down noise reduction V-type and regulates ball valve.
Background technique
Existing ball valve; Mainly contain compositions such as valve body, valve seat, spheroid, valve rod, valve gap, the O shape mouth structure that its spheroid is commonly as shown in Figure 1, the shortcoming of this structure be can not reduce pressure, reduce noise, the control flow velocity; When aperture 30%, do not have to regulate and change the adjusting function extreme difference.
Summary of the invention
The purpose of the utility model is: provide a kind of step-down noise reduction V-arrangement to regulate ball valve, avoid High Pressure Difference, noise is big, flow velocity is high and adjusting function extreme difference phenomenon, it is applicable to that the High Pressure Difference pipeline reduces pressure, controls flow velocity, reduces noise and Flow-rate adjustment.
The technical solution of the utility model is: it comprises valve body, valve seat, the adjusting of step-down noise reduction V-arrangement spheroid, valve rod and valve gap; Valve gap is installed on the valve body; Step-down noise reduction V-arrangement is regulated spheroid in valve seat is installed the valve pocket of valve body, and valve rod connects step-down noise reduction V-arrangement and regulates spheroid; It is characterized in that: have enough V-shape holes on the side of step-down noise reduction V-arrangement adjusting spheroid, have many tortuous apertures simultaneously, V-shape hole communicates with tortuous aperture.
The beneficial effect that the utility model is compared existing technology is: it can improve effectively and reduce High Pressure Difference, controls high flow rate, reduce noise; Can realize also that when little aperture flow accurately regulates; Medium through tortuous aperture gradually step-down slow down, to reduce pressure, improved product working life to the downstream valve seat; Reduce noise protection environment, have interchangeability with conventional ball and can dismantle easily or safeguard equally.
